GOP OR BOBBIN WINDING MACHINE.

Patented May 6, 1913.

To all whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at. Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Im rovements in Cop or Bobbin Winding Macliines, of which the following is a specification.

My invention relates to a cop or bobbin winding machine, and paricularly to a cop winding machine of the type shown and described in the U. S. Letters Patent, No. 976,698, which automatically winds cops, bobbins, or spools, and the object of my 1nvention is to improve upon the construction of the cop winding machine of the type referred to.

My invention in this instance particularly relates to the trumpet guide or shaper, and the individual traverse motion combined therewith for each separate cop or bobbin, and a guide, independent of the spindle on which the cop or bobbin is mounted, to control the direction of movement of said trumpet guide or shaper.

I have only shown in the drawing a detached portion of a cop winding machine of the type above referred to, with my improvements applied thereto, suflicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawing :Figure 1 is a side view of the spindle drive mechanism of a cop winding machine, and my improvements combined therewith, looking in the direction of arrow a, Fig. 2. Fig. 2 is a plan view of the parts shown in Fig. 1, looking in the direction of arrow 6, same figure, and, Fig. 3 is a section, on line 3, 3, Fig. 1, looking in the direction of arrow 0, same figure, showing the trumpet guide, and the traverse mot-ion combined therewith.

In the accompanying drawing, 1 is the back girt of the machine, on which is mounted a stand 2, havin the upwardly extending ears 2 carrying a bolt 3, on which is pivotally mounted the downwardly extending lug 4, which is rigidly attached to the spindle bed 4. The other end of 'the stand 2 is provided with a bolt or stud 5, which has loosely mounted thereon the hub of a lever '6. The'upper end of the lever 6 is made forked and carriesa stud 7, on which is pivotally mounted the lower end of a link 8. The upper end of the link 8 is pivotally connected with a bolt 9, on the rear part of the bed 4, see Fig. 1.

'When the lever 6 is in the position shown in Fig. 1, the link 8 bears against the end of a screw bolt 10, which is adjustable in and out in a downwardly extending projection 4 on the spindle bed 4. The rear portion of the spindle bed 4 is raised, to cause the driving belt, not shown, to be tightened on the pulley 11, to rotate the spindle 12, which spindle is adapted to rotate loosely in bearings 4 and4 on the bed 4, see Fi 2. The inner end of the spindle 12 is provided with an enlarged head 12, which is adapted to hold the butt or head 13' of a cop or bobbin 13, on which the thread is to be wound.

All of the above mentioned parts may be of the usual and well known, construction, and are fully shown and described in U. S. Letters Patent, No. 976,698, above referred to.

I will now describe my improvements, which consist particularly in moving the trumpet guide, and having an individual traverse motion combined therewith, for

each separate cop or bobbin.

The spindle 12 has mounted thereon, in this instance, the hub 14, see Fig. 2, of a pinion 14, which pinion meshes with and drives a gear 15, having its hub 15' fast on the elongated sleeve 16, which sleeve preferably revolvcs in suitable bearings 4 and 4", on arms 4 and 4" which extend out from the spindle bearlngs 4 and 4 see Fig. 2. The sleeve 16 is prevented from having a side motion by two collars l7 and 1 8, secured to the sleeve 16, one on each side of the bearing 4. The sleeve 16 is preferably provided with a centrally extending hole of square shape, which loosely receives the square shaftv 19, which is adapted to be rotated by the sleeve 16, through the rotation of the pinion 14 on the spindle 12, meshing with and rotat-ing'the gear 15 "on the sleeve 16. l i

The square shaft 19, which extends in a horizontal plane, has its end suitably fulcrumed in a bearing 20', which forms a part of the trumpet guide 20, see Fig. 2. The trumpet guide 20 has the hubs 20" and 20", loosely mounted on the horizontally extendiug guide rods 21 and 22, see Fig. 2, to have a sliding reciprocating motion thereon. The rods 21 and 22 are adjustably secured in crank pin 29, which the clamping bosses 4 and 4, see Fig. 2, on the spindle bed 4. To the outer ends of the rods 21 and 22 is secured the transverse bar 23. A boss 20 on the trumpet guide 20, see Fig. 2, is adapted to hold the cylindrical portion 24' f the trumpet or shaper 24, which is adapted to form the shape of the bobbin or cop 13, in the usual way.

A chain 25, see Fig. 1, is secured at one end to the trumpet guide 20, and passes over a guide sheave 26, loosely mounted on the bolt 3. A weight, not shown, is preferably secured to the other end of the chain 25, which weight acts to yieldingly move the trumpet guide 20, and the trumpet 24, toward the cop 13, to have the thread wound on the butt 13, in the usual way. The

square rod 19 has in this instance secured on located tapered head its end an eccentricall ich is adjustably se- 19, see Fig. 2, to w cured, by a screw 27, see Fig. 3, the cap 28 forming a crank .device, and having the in this instance is of round shape, to extend loosely within the ball shaped end on the upper end of a downwardly extending connector 30, to form a ball and socket joint connection. The lower end of the connector 30 has a ball shaped end and is pivotally connected to a pin or stud 31 having a round shaped end, to form a ball and socket joint connection.

The stud 31 is adjustably secured to the end of an arm 32, which arm has its hub 32, see Fig. 3, pivotally mounted on a stud, see Fig. 1, secured to a bracket 20, see Fig. 3, on the trumpet guide 20. Extending upwardly from the hub 32 is the traverse guide lever 34, which has its upper end provided with a thread guide 35, which is suitably held in the end of the transverse guide lever 34, and is adapted to ide the thread in the usual way, to form t e cop 13, to be wound in the usual way.

A stud 36, see Fig. 3, on the trumpet guide 20, has loosely and centrally mounted thereon a lever 37, which is adapted to engage a collar 38, adjustably secured on the horizontally extending rod 39. The rod 39 has a knob 39 on its outer end for the operator, so that said rod may be manually operated to stop and start the rotation of thespind1e,12.

,After the cop 13 is wound to a predetermined amount, the lever 37 will engage the collar 38, and move the rod 39 toward the right. The innerend of the rod 39 is suitab y secured to one arm of an angle lever 40, see Fig. 1, which has its hub loosely mounted on the stud 3. The second arm of the angle lever 40 has pivotally connected thereto one end of a connector 41. The other end of the connector 41 is pivotally connected to the stud 7 on the lever 6, see Fig. 1. The moving of the rod 39 to the right in the drawing, causes, through intermediate i nected same, and means to rotate said shaft.

scribed, a spindle 'a bobbin or carrier, a trumpet or shaper adapted to be moved by the increased mass connections to the lever 6, said lever 6 to rock, and through the link 8 causes the spindle bed 4 at its outer end to be lowered, to loosen the belt on the pulley 11, and cause said pulley 11 to rest on the friction device 42 on the upper end of the arm 43, secured to the cross girt 1, see Fig. 1, and stop the rotation of the spool, all as fully described in the U. S. Letters Patent, No. 976,698, above referred to.

In my improved construction the trumpet guide is movable in the direction of the length of the cop or bobbin to be wound, and there is an individual traverse motion combined therewith, for each separate cop or bobbin, and a guide, comprising in this instance rods 21 and 22, independent of the spindle on which the cop or bobbin is mounted, to control the direction of movement of said trumpet guide.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is t- 1. In a winding machine" of the class described, a spindle mounted to rotate on a spindle bed, and said bed, mounted to turn on a pivotal center, a trumpet or shaper, adapted to be moved by the yarn wound on a bobbin or carrier, and said bobbin or carrier, connected with said spindle to rotate therewith, and a guide to control the movescribed, a spindle to cause the rotation of a bobbin or carrier, a trumpet or shaper adapted to be moved by the increased mass of yarn wound on said bobbin or carrier, a traverse guide mounted to move with said trumpet or shaper, a crank device also mounted to move with said trumpet or shaper, a rotatable and slidable shaft conto said crank device, to operate the 3.
